Question

A fuel dealer makes a profit of shillings 520 for every 1000 liters of petrol sold and shillings 480 for every 1000 liters of diesel sold. In a certain month the dealer sold twice as much diesel as petrol. If the total fuel sold that month was 900,000 liters, find the dealer’s profit for the month

Answer 1

300*520 + 600*480

Answer 2

diesel = 2*petrol

1) d = 2p

2) d + 2p = total sold = 900,000

See if you can find p and d from those two equations now and then the profits after that.
